What are the types of kidney cancer?
The most common type of kidney cancer is renal cell cancer. Renal cell cancer is a disease in which cancer cells form in the lining of the kidney’s tubules (tubes). These tiny tubes filter and clean blood that passes through the kidney.
Urothelial cancer is another form of kidney cancer. This is a disease in which cancer cells form in the renal pelvis and the ureter.
The renal pelvis is the top of the ureter, a tube that connects the kidney to the bladder. When the kidney filters blood, the waste transforms into urine and collects in the renal pelvis before passing through the ureter and into the bladder.
